Mugen MBX 7075 HARD Front and Rear Axle Shaft Upgrade - Arrowmax AM-MBX-E0221  [AM-MBX-E0221]

MBX Front/Rear Hardened Axle Shaft

This front and rear axle shaft is an Arrowmax option part intended for Mugen MBX models, designed for RC driveline applications. The "7075 HARD" designation is taken from the part name and indicates the hard-treated 7075 spec provided by the supplier.

The shaft works as a replacement or upgrade to restore precise alignment and reduce drivetrain play on MBX cars, useful during setup or race preparation. Fitters should measure runout and check clearances to ensure the shaft mates cleanly with existing wheel hexes, diff outputs, and bearings.

Installation guidance: remove the old shafts and assess bearings and hexes for wear, use thread locker on appropriate fasteners, and confirm free rotation before final assembly. Note that increasing axle stiffness or tightening fit can influence driveline lash and transient traction, so re-evaluate related suspension and gear settings after installation.

Use this Arrowmax shaft when you need a direct-fit, hard-treated replacement for front or rear axle maintenance and setup on Mugen MBX cars.
